Hi
Kaplan is good, but Manhattan would be better as a mock exam. However, I do not think a different mock exam would bring a different story to the table with 150 in verbal.
In such a short amount of time is difficult to fill the gap: assuming you need 160 only that would be 10 points. A good challenge.
The problem with TC is that knowing vocabulary is just part of the story. It would be best if you improved your grasp of the sentence's meaning as well.
